flic it known that ll` JOHN ll. tllciiuimr., a citizen of the UnitedStates, residingi at tilt. lilouis, in the State of ildissouri, haveinvented new and useful improvements in Heaters, of which the following'is a specification.

My present invention relates to injiprovements in heatinpY apparatus andmore especially to hot water or stean'i-lieating systems lair being'therebyT humidified and also deprived of any dust. and means is alsoprovided for maintaining a Ysupply of water in 'the vessel from theradiator. this supply of water being preferably maintainedautomatically.

To these and other ends, the invention consiste in certain improvements,and combina-V tions and arrangements of parts, all as will behereinafter more fully described, the novel features beine pointed outparticularly in the claims at the end of the specification.

ln the accompanying drawing Figure 1 is a side elevation of a radiatorprovided with a shield, water vessel, and water supply means embodyingthe present invention;

Fig. 2 represents a transverse section of the upper portion of theshield and coperating parts;

Fig. 3 represents a horizontal section of a portion of the shieldshowing the water vessel and its coperating parts in top plan;

Fig. t is a diagrammatic view showing' the manner in which the watersupply valve may be applied to a steam radiator.

Similar parts are designated by the same reference characters in theseveral views.

The present invention is applicable generally to radiators or equivalentmeans for Specification el .Letters Illatent. iltt llt n t nil 1915.iiler'tl No. 20.590.

heating the air ol' a rooin. apartment or the like, it being1 especiallyadapted to the. stcaui or hotl water hcatiurgr santi-nis' as uscd inhouses and ollices. rlllhe prclcrrcd construction is shown in theaccompanying drawing4 and will he luneinattcr described in detail. butit is to lie understood that the invcntion not restricted to theparticular consti-urtion shown, as ctluivalcnt constructions within thescope ot the annexed claims arc contempla ted.

ln the present instance. l designates a radiator otl the ordinary I vpewhich 1ua v he eoiniected to the steam or hot u'atcr pipes 2 ol theheating system. .lccordiun' to the present invention. the radiator issulistan-4 tially inclosed by a shield Il. this shield lie-- ingprefcralily constructed of wood having' an asbestos or heat insulating,-lining l-, and it open at thebottoln to adniit air to the radiator.designating' an opening in one of the side walls of the shield. Theshield is also provided with an opening tl in the top through which theheated air from the radiator passes from the shield into the room orapartment to he heated. Preferably, the top of the shield is formed witha cap having the upwardly and .inwardly slopingi wall- 7 andthedownwardlyY and inwardl)Y sloping walls 8, the lower edge ol the latterwall forming a dependingl tiange 9.

A vessel to contain water is located beneath the outlet opening inthetop of the shield and serves to dampen or huinidify the heated air andto remove therefrom any dust suspended in the air. In the presentinstance. a vessel l0, preferably in the form of a shallow pan, isprovided and is located beneath the outlet opening in the shield, thebottoni of the vessel or pan being preferably depressed toward itscenter in order to insure a proper distribution of the water therein,and the sides 11 of the pan or Vessel are preferably flared or arrangedsubstantially'in parallelism with the downwardly and inwardly slopingwalls 8 surrounding the opening in the shield, a downwardly slopingpassageway being thereby formed between the sides of the pan and thewall 8 through which the heated air is directed vinto Contact with thewater contained in the pan or vessel. The pan or vessel is supported ontitl a frame 12. T he present invention provides means whereby a supplyor water will be automatically maintained in the pan or vessel and, asshown, the pan or vessel is so mounted that it may move vertially andthereby control the'flow of water thereto. ln the present instance, theframe 12 provided with a suitable number of vertical plungers or rods13, and` these plungers or rods slide vertically in talles or guides 11iand rest upon springs 15. The strength ol the springs and the height otthe pan are adjusted by set-screws lolitted into the bo",- toms of thetubes or guides. The tubes or guides lll may be readily supported withinthe shield by suitable bracketsv 1T. rl1 he radiator is provided with a.valve 18 adapted to discharge water from the interior thereof, a pipe 19extending from this valve to the pan. The opening and closing of thevalve 18 is controlled automatically according to the height ol2 thewater-containing pan or vessel. ln the construction' shown, the handleor lever 20 of the valve is connected by a rod 21 to the verticallymovable vessel supporting .iframe 12. The arrangement is such that whenthe vessel or pan contains a suitable amount of water, its weight willbe sufficient to hold the pan and its supporting :trame 12 in depressedposition. and against the compression ol the springs 15, the valve 18being thenl closed so that the flow of water from the radiator to thelpan is cut oil, but when the amount of water in the vessel or panl hasbeen diminished, by evaporation, sui'liciently to reduce the weight ofthe pan and allow the springs 15 to elevate it, the rod 21 will he drawnupwardly by the consequent rising of the frame 12 and the valve 18 willbe opened to admit water from the radiator to replenish the water in thepan, and when a sullicient amount of water has been introduced into thepan, the latter will settle or move downwardly under the weight of thiswater and the valve 18 will be thereby closed. llhis arrangement alsoserves to vent such airfrom the radiator as may accumulate in the topthereof, thereby insuring a most elhcient circulation in the heatingsystem.

lln applying lthe invention to hot water heating systems,'the valve 18may he connected directly to the upper portion of the radiator, as shownin Figs. 1 and El, but in applying the same to. steam-heating systems,the water of condensation is drawn from the lower portion of theradiator and is forced by the steam pressure in the radiator up tothevalve 18. Fig. 3 shows an arrangement of this character, the water olcondensation being drawn from the bottom ol the radiator through a pipe29) into a water-coln lecting tank or collector :'23 and being liftedtherein. `wardly sloping arrangement oi the wall 8,

:1,2 avea -from the latter through a pipe @el to the valve 18 by thepressure of the steam within the radiator.

' lccording to the present invention, all the air to he heated entersthe bottom ol the shield, and alter passing or Flowing through theradiator, the air thus heated discharges through the opening in the topoli the shield, hut all the heated air discharging from the top oi theshield must come in contact with the water contained in the pan orvessel, the heated air being thereby dampened or hu midilied to theproper degree and also deprived ol such dust as maybe suspended @wing tothe downwardly and inandthe parallel arrangement ol the sides l1 of thepan, the heated air 1s directed clownwardly and into contact with thesurface oi the water in the pan or vessel, and as the. water in lthe panor vessel is heated from radiator, the heated air comme,n in Contactwith this water will be sufficiently dampened or humidilied and the dustsuspended in the air will he precipitated and collected in the pan.

l claim as my invention l. A radiator shield having a heated air outletprovided with a downwardly and inwardly inclined marginal llange, and awater vessel located below and opposite to said outlet and supported toautomatically move vertically toward and from saidsdutlet ac'- cording;to variations in the amount et" water in the vessel, said vessel havingupwardly and outwardly inclined sides surrounding the lower edge of saidmarginal flange and forming with the latter a downwardly andA inwardlyextending air outlet passage operative to direct the heated air Jfromthe shield onto the surface el the water in the vessel in the form ol' ahlm and in a direction inwardly toward the center of the vessel.
